Kids who care about the natural world can learn about ocean life with this detailed LEGO® Friends Sea Rescue Boat toy building set for ages 7 and over. The set comes with a buildable catamaran that doubles up as a laboratory, plus a small submarine toy. Kids can act out sea rescue stories as they roll the boat over the rubbish to capture it in the boat’s nets, ready for recycling. Nova and Aliya didn’t think that they had much in common with one another but are becoming closer as they take on this shared mission.

Boost the fun

Kids can enjoy an easy and intuitive building adventure with the LEGO Builder app. Here they can zoom in and rotate models in 3D, save sets and track their progress. This set can be combined with LEGO Friends sets 41736 and 41752 for even more ocean rescue adventures (sets sold separately).
